/**
* An event which indicates a change to the {@code Component}
* hierarchy to which {@code Component} belongs.
* <ul>
* <li>Hierarchy Change Events (HierarchyListener)
* <ul>
* <li> addition of an ancestor
* <li> removal of an ancestor
* <li> hierarchy made displayable
* <li> hierarchy made undisplayable
* <li> hierarchy shown on the screen (both visible and displayable)
* <li> hierarchy hidden on the screen (either invisible or undisplayable)
* </ul>
* <li>Ancestor Reshape Events (HierarchyBoundsListener)
* <ul>
* <li> an ancestor was resized
* <li> an ancestor was moved
* </ul>
* </ul>
* <p>
* Hierarchy events are provided for notification purposes ONLY.
* The AWT will automatically handle changes to the hierarchy internally so
* that GUI layout and displayability works properly regardless of whether a
* program is receiving these events or not.
* <p>
* This event is generated by a Container object (such as a Panel) when the
* Container is added, removed, moved, or resized, and passed down the
* hierarchy. It is also generated by a Component object when that object's
* {@code addNotify}, {@code removeNotify}, {@code show}, or
* {@code hide} method is called. The {@code ANCESTOR_MOVED} and
* {@code ANCESTOR_RESIZED}
* events are dispatched to every {@code HierarchyBoundsListener} or
* {@code HierarchyBoundsAdapter} object which registered to receive
* such events using the Component's {@code addHierarchyBoundsListener}
* method. ({@code HierarchyBoundsAdapter} objects implement the
* {@code HierarchyBoundsListener} interface.) The {@code HIERARCHY_CHANGED} events are
* dispatched to every {@code HierarchyListener} object which registered
* to receive such events using the Component's {@code addHierarchyListener}
* method. Each such listener object gets this {@code HierarchyEvent}
* when the event occurs.
* <p>
* An unspecified behavior will be caused if the {@code id} parameter
* of any particular {@code HierarchyEvent} instance is not
* in the range from {@code HIERARCHY_FIRST} to {@code HIERARCHY_LAST}.
* <br>
* The {@code changeFlags} parameter of any {@code HierarchyEvent} instance takes one of the following
* values:
* <ul>
* <li> {@code HierarchyEvent.PARENT_CHANGED}
* <li> {@code HierarchyEvent.DISPLAYABILITY_CHANGED}
* <li> {@code HierarchyEvent.SHOWING_CHANGED}
* </ul>
* Assigning the value different from listed above will cause unspecified behavior.
